A beam of light makes an angle of 13.0 with the normal of a mirror made of 4.70-mm-thick glass silvered on the back. If the index of refraction of the glass is 1.30, how far is the point at which the beam leaves the glass surface (after being reflected from the silver backing) from the point at which the beam entered the glass? Provide the answer in mm.
